Xanthicus was the eighth month of the Macedonian year, and corresponded to our April (see table on p. 403, below). The martyrdom of Apphianus must have taken place in 306, not 305; for according to the direct testimony of Lactantius (de Mort. pers. chap. 19; the statement is unaccountably omitted in the English translation given in the Ante-Nicene Fathers), Maximinus did not become Cæsar until May 1, 305; while, according to the present chapter, Apphianus suffered martyrdom after Maximinus had been raised to that position. Eusebius himself puts the abdication of the old emperors and the appointment of the new Cæsars early in April or late in March (see above, chap. 3, §5, and the Syriac version of the Martyrs, p. 12), and with him agree other early authorities. But it is more difficult to doubt the accuracy of Lactantius’ dates than to suppose the others mistaken, and hence May 1st is commonly accepted by historians as the day of abdication. About the year there can be no question; for Lactantius’ account of Diocletian’s movements during the previous year exhibits a very exact knowledge of the course of events, and its accuracy cannot be doubted. (For a fuller discussion of the date of the abdication, see Tillemont’s Hist. des Emp., 2d ed., IV. p. 609.) But even if it were admitted that the abdication took place four or five weeks earlier (according to Eusebius’ own statement, it did not at any rate occur before the twenty-fourth of March: see chap. 3, above, and the Syriac version, p. 12), it would be impossible to put Apphianus’ death on the second of April, for this would not give time for all that must intervene between the day of his appointment and the republication and execution of the persecuting edicts. In fact, it is plain enough from the present chapter that Apphianus did not suffer until some time after the accession of Maximinus, and therefore not until the following year. Eusebius, as can be seen from the first paragraph of this work on the martyrs, reckoned the beginning of the persecution in Palestine not with the issue of the first edict in Nicomedia on Feb. 24, 303, but with the month of April of that same year. Apphianus’ death therefore took place at the very close of the third year of the persecution, according to this reckoning.
